CCENT/CCNA [H] study group

I have the questions from the subnetting made easy thread down to a science. Using that method I can easily find all the info about an ip address and subnet mask. What I am trying to figure out now is a quick and easy way to do the subnet design questions. Like when you are given an IP address and need to choose the proper subnet mask for a certain number of subnets or hosts. LIke the questions below.


Question: You are designing a subnet mask for the 172.25.0.0 network. You want 3000 subnets with up to 9 hosts on each subnet. What subnet mask should you use?

Is there an easy method to solve those questions? the other ones that the subnetting made easy thread covers is extremely easy.

There are charts you can try to memorize:

Check for the number of borrowed bits you would need for that many subnets. Then see if the number of hosts for each subnet will meet the needs.

If you need 9 hosts per subnet, then you know you need a /28, which gives you 16 IPs with 14 usable for hosts. Go with the easiest of the two requirements.
 
how big is the paper you get when you take the exam to rite stuff on? I am looking to come up with some kind of table I can use.

Somebody mentioned to make this

2 4 8 16 32 64 128 256 512 1024 2048 4096
 
Many moons ago .... I was given two dry-erase boards the size of a normal 8x11
sheet of paper.

I made tables like you showed ..x4's, x8's , x16's.
The table helped on my initial pass of the CCNA..but did no good
on my recert 3 years later.

I don't even know if they still allow you time before starting the exam anymore.
If they do, draw the table and write any info you can fit on half the space they give you.

I used more space drawing out the small networks they wanted me to config.

If I happen to try the CCNA again, I'd find a way to do subnetting (bit shifting) in my head
like shown in some of the post here.
 
so you could just write out 2 4 8 16 32 64 128 256 512 1024 2048 4096

and then count over until you have the number of subnets you need?

so for a class B address you need at least 32 subnets. You would count over to 32 and call it 5 bits. then add 5 to 16 = /21?
 
If you think you need more space to write just ask for more. I don't think there really is a limit for that.
 
Looks like I still need some ram for the last supported IOS on my gear and some patch cables from mono price to arrive, but my lab is nearly done. Only thing not pictured is the 3550 I need warrantied, a 3500, and 3620 I lent to a friend for studying.

1x 3640 w/ 1FE2W + Wic T1
Grand total without the ram is $210 (NOT including the 881W, that was another $200 impulse buy...)

Quick question for you guys, would you move the ASYNC32 to a different router? And other then memory upgrades, any other hardware I should be watching out for to add (CCNA planned, possible CCIE.)
 
I'm looking at equipment for lab practice and implementation in a home network, I was wondering is the 892 router a good choice as in does it provide all of the features I need for my CCNA? How far do you think I can go with it before I need something more robust? What semi-modern switch would you guys recommend for a decent price?

Nice stuff! how did you get it so cheap?
 
Ewaste recyclers :) There are 3 around Portland. The 2950-24TT and 3500 were $10/each. I mainly spent $80 on ebay for cards/cables/ NM's to get it more complete.

I have not done much reading yet, but quick question on this lab. Is it worth investing ($60-80 off ebay/monoprice) on a Serial setup? (Quad serial NM, several cables, some Serial WIC's and maybe a WIC T2?) Or will the Wic-T1's do what I need for CCNA?
 
Depends, I remember when I used to use the old pinned serial cables, they were gold pins, so each pin was about 100$ a pop. But I remember when I did my CCNA lab stuff we used three routers and connected them together by serial, so it really depends on how you're connecting things together.

No shit? I've been putting off going to one of those. Isn't there one up by Jantzen Beach? They have used racks that I was going to pick up. :) Nice setup and some good prices!
 
Taking my CCNA tomorrow. Using this for subnetting. Easy to remember, and you pretty much can work out subnetting in seconds with this.

I try to to "junk store" hunting with a few friends once a week. Did not know there were any up that direction. I mainly visit Freegeek and EcoBinary.

From my reading, a WICT2 + a cheap 4 port serial + monoprice cables is not a bad investment for CCNP. So, I remembered one of the stores I visit had a WicT2, so now I just need to win the $10 4 port serial card and buy a few additional cables :).

Good luck on the test! Let us know how it goes
 
Well, I took my test. Got a 785/1000. At least I know what to expect now. I got like 3 questions on there about sub-netting and that's it.
 
Its hard, no trick questions, very detailed, study the questions carefully. Just study the stuff, and make sure you have a clear understanding of everything. And grow a third testicle, you'll need it after the test rips one off.

This. I've done like four of the Cisco exams and I still get jitters going into them. And its like an adrenaline rush after you pass. :p
 
Just passed my CCENT with a score of 862 and almost an hour left on the exam. I thought it was pretty easy. On to the ICND2.

I will post more later when I am home.
 
I thought the test was pretty easy. Aside from the simulations you get I actually thought it was easier than the Net+ but this may be because I have been doing networking and studying this stuff for a long time along with being a Network Engineering major so i pretty much think about networking 24/7. The test was very fair and straight forward. If you study the material and know all the concepts and how networks work than you should not have much trouble. I actually thought I was going to get a perfect score. I am not sure which questions i got wrong but there were a few that could have had or seemed to have different right answers so i think i did bad on those.

What amazed me the most was how fast i blew through the test, when I was done I had almost a good hour left. I heard time management was the biggest issue with this exam but I thinking studying hard, knowing the material and being good with networking in general help you speed through it.

All the practice i did on subnetting payed off as well! Know your subnetting! I am going to post a guide here on how I learned to master subnetting to the point where I can do any possible questions within seconds. For the dry erase board all I did was write down this simple chart,

128 192 224 240 248 252 254

2 4 8 16 32 64 128 256 512 1024 2048 4096 8196 16384 32768 65536

I had this pretty crappy dry erase marker that was fat and i had to put the multiples on 2 lines:rolleyes: then I got a question where i needed to figure out a subnet and i wanted to write out and count up the block sizes but it turned out that the marker dryed up from sitting out and was now worthless:rolleyes: luckily i could do it in my head.

For study material I used the following books along with any practice tests(found on google and from my study books), flashcards, blog posts etc.. I could find on google.

Grats on the pass man. I just used only Odom's book to study for the ccent which was my big mistake. I barely passed on my first try. Having another book or two to get a different angle on things really helps out as I've found out with my icnd2 studying. CBT Nuggets is good too if you can afford it

Damn you. I got 850. :) Congrats, man. It was WAY easier the second time I took it. First time, I was pretty damn nervous. But, it gave me a good idea of what to work on. I got 3 100%'s on my score sheet, and my subnetting was at 78%. Not too bad.

I tell you what, though. This helped me out a lot. Really sped me up (didn't need it. Passed in 30 minutes). Very glad it was posted, and THANK YOU Kaiga!

Congrats to you as well! we can study the ICND2 together! I got an 89% on the subnetting.
 
Grats AMD_Gamer!
Well I have my CCNA booked again for July 25th. Balls to the wall studying this time.
 
Im working on ICND2 right now too. Kinda split my studying between this and a bunch of firewall stuff atm for work. Re-doing our vpn concentrators
 
Grats on the pass, AMD_Gamer! Giving me some motivation to find time to study for the exam despite my full academic load and full time job.
